Sample and acceptance review
Request a fit sample and the maker’s installation guidance. Check the assembly according to the responsible builder’s procedure.
A common purchasing mistake
A guard’s nominal size does not prove adequate clearance for every propeller sold under that size.

Procurement checks for guards and ducts
A guard or duct can fit its mounting holes while leaving inadequate clearance elsewhere. It should be reviewed with the propeller, motor and frame configuration.
